zfs updated in freebsd 7 2

FreeBSD 7.x has been using version 6 of ZFS, and originally only 8.0 was going to have the newly updated ZFS version: 13.

Last week the core team MFC’d (Merge From Current) the ZFS updates to 7.2, so I cvsup’d and re-build my server’s kernel and world ( with a simple “make buildworld && make buildkernel && make installworld && make installkernel ), rebooted, and now I have the latest ZFS version running:

[root@server ~]> zpool upgrade -v
This system is currently running ZFS pool version 13.

The following versions are supported:
